Nokia Micro SD card help.

Help!.

My Nokia E71 phone decided to delete all the messages saved to my 2gb micro sd card. Is there any way to find them? I know it sounds silly but I have texts saved regarding jobs, information links for assignments, contact info that I hadn't saved yet.

I really really would appreciate any help with this.

There's no password on the card and I didn't accidentally eject it or anything. Just after hanging up a phone call, I went into my inbox and they were all gone.
